Answer:
To find : position of centre of mass of a 2 particle system
Given: position vector of the particles.
( let the position vectors be x1+y1 and
x2+y2 for 1st and 2nd particle respectively)
Now, the position of centre of mass can be found by this method for any number of particles.
You need to calculate individually for x axis and y axis.
x position = (m1*x1 + m2*x2)/(m1+m2)
y position = (m1*y1 + m2*y2)/(m1+m2)
We are considering the origin (0,0) as the reference point.
Please add the vector sign above x and y and to the position.
